Each of the functions in Problems 5 to 12 is given over one period. For each function, sketch several periods and decide whether it is even or odd. Then use (9.4) or (9.5) to expand it in an appropriate Fourier series.

- Suppose that a lake is stocked with N fish of the same age, and that M is the mortality rate of the fish (the fraction of the fish that will die of natural causes during the year), and F is the fishing rate (the fraction that will be caught commercially). Then the number of fish C that will be caught during the year is given by the formula C=FN/ M+F; in this formula, M and F must be entered as decimal values. (a) Suppose that the lake is stocked with 5500 catfish at the beginning of the season and that the fish have a 7% mortality rate. If the catfish are removed at a fishing rate of 25%, what are the appropriate values of the quantities N, M and F in this situation? Use these to determine how many catfish will be caught by fishing from the lake. (b) Treat N and M as parameters with the same values given above. Then complete this table of function values of C in terms of F : (c) If this function C = C(F) were graphed, would it be an increasing or decreasing function? Would it…arrow_forwardA medical test is available to determine whether a patient has a certain disease. To determine the accuracy of the test, a total of 9700 people are tested. Only 100 of these people have the disease, while the other 9600 are disease free. Of the disease-free people, 9300 get a negative result, and 300 get a positive result. The 100 people with the disease all get positive results. Round your answers to four decimal places, if necessary. Given that a person gets a positive result, what is the probability that the person actually has the disease?arrow_forwardQuestion 12 Find the GCF of 9x', 12x², and 6 O 12 3x 6. No new data to save.
